Why it sounds like that

Raise the fifth of B major from F♯ to F♯♯ and you get B ionian augmented. The scale keeps the major third and major seventh while the sharp five creates a whole-and-a-half step between E and F♯♯. Compare it with B major to hear that single altered degree.

When to use it

Use it over B augmented or B augmented major 7th. The sharp five also fits dominant-function passages in B major. Try it in jazz or fusion lines where the augmented colour is explicit.

Which position to practise

Practise Box 1 first. It places the root on string 6, fret 7 and covers frets 0–3, making it easy to connect to open-position B major shapes.
